The Shift-BF Batch 2 Bottom Feed Rebuildable Dripping Atomizer by bOOSTLAB Korea is a bottom-feed capable micro dripper that is designed for maximum flavour production with minimal power requirements!

Original Batch 1 Shift-BF Rated 10 out of 10 by Todd Reviews! Click here to watch the review!

Now back, as the Batch 2, bringing new materials and enhancements to one of the best bottom feed atomizers on the market!

New changes include:

  • Stainless steel cap replaces the black PEEK cap of batch 1. New cap is 1mm taller than batch 1, for better air flow.
  • Wide bore Ultem drip tip replaces the black Delrin drip tip.
  • Larger air inlet with revised shape, allowing for a wider range of usable air flow settings. Air flow can now be made even tighter or looser than the batch 1.

Note: Batch 1 and Batch 2 caps and decks are NOT interchangeable!

MinWoo Lee of BoostLab is known for innovative easy-to-build deck designs that present piles of flavour, and this Shift-BF atty does NOT disappoint! Using a build deck and air flow design that is somewhat similar to the Shift Atty RTA, the Shift-BF takes that great design, slams everything down into a much shorter height, opens up the air flow a bit more, and minimizes the juice reservoir to turn this into a monster of a flavour dripper!

Out of the box, the Shift-BF Batch 2 Bottom Feed Rebuildable Atomizer is bottom-feed ready, for use in your favourite bottom feed squonker, but a screw that is included in the spare parts kit can be screwed into the bottom of the 510 pin to block it off and turn this into a flavour punching dripping atomizer!

Air flow is fully adjustable from fully closed down, to a restricted lung hit when wide open and everything in between for flavour chasing mouth-to-lung vapers.

The deck is improved over the Shift Atty, now allowing users to install a single horizontal coil, single vertical coil, or dual vertical coils! These options increase build creativity options! Can use cotton or stainless steel mesh for maximum flavour production.

From the outside, the Shift-BF RDA is an extremely stout atty, with clean design lines, a 22mm outer diameter, and sleek looks. Its subtle and small size will make it look great on any device.

The outer cap is made from stainless steel.

The included wide bore drip tip is made of Ultem, to further insulate the user's mouth from heat.

If there is a flavour RDA for 2017, the Shift-BF Batch 2 is likely to win!
